The copy-router-config menu item, which is located in the Backtrack menu (Backtrack > Vulnerability Assessment > Network Assessment > Cisco Tools), is a handy little Perl script put together by Muts himself. Once you click on the menu item it will launch a terminal window in the /pentest/cisco/copy-router-config directory so you will have direct access to the 35 line Perl script which servers a single purpose. That purpose is to copy an entire router configuration file from a Cisco device if you have a RW (read/write) community string for the router.
